WICK-RAISING DEVICEFOR CENTRAL-DRAFT LAMPS.

SPECIFICATION forming part-of Letters Patent No.4466,919, dated January 12, 189,2. Application filed November 28, 1890. Serial No. 372,841. (No model.)

To @ZZ whom it may concern: per end of said rod e is provided witha knob Be it known that `I, WILLIAM M. HOERLE, e for convenience in rotating said rod from a resident of Allegheny, in the county of the exterior of the fount.

Allegheny and State of Pennsylvania, have The wick-raiser proper is composed of the 55 5 invented a new and useful Improvement in bifurcated rod f, provided with the threaded Tick-Raising Devices for Central -Draft connection g, through which the wick-raising Lamps; and I do hereby declare the following rod e passes, the threads on said rods engagto be a full, clear, and exact description ing with the interiorly-threaded face of said thereof. connection g, whereby upon the rotation ot' 6o 1o My invention relates to wick-raising devices the threaded rod e the bifurcated rod f may for what are known as central-draft lamps. be raised or lowered, as may be desired.

In sition of the locking device when the clutches order,howe`ver,tosecurelylock saidclutches in are released. Fig. 2 is a plan View of the their bearings and so prevent any swinging 8o 3o wick-raiser proper, showing` the manner in movement on their part, a U-shaped arm j is which the clutches are journaled within thepivoted to the arms 7L of the bifurcated rod arms of the bifurcated rod. Fig. 3 shows a f. Said U-shaped army' is provided with the modiiied form for releasing the clutches or fingers 7c, adapted to engage with the vertical locking the same. Fig. 4: is a sectional view portions i of the clutches 7l. The forward 85 35 showing manner of journaling clutches on the ends of the arms h of the bifurcated rodf are armsof the bifurcated rod. slightly turned back to form the iianges Z, Like letters indicate like parts. with which the fingers 7o engage to further My invention is applicable to any of the aid in locking the clutches securely in their ordinary forms of central-draft lamps, of bearings. The normal position of the U- 9o 4o which a in the drawings represents one form shaped arm j, as shown in Fig. l, is such that suitable for the illustration of my device, said the linger 7o will engage with the flanges Z, lamp being provided with the central draftwhile the rear portion of said arni j is uptube b and encircled by the wick d. Any wardly inclined from its point of connection convenient form of wick-raising rod may be with the arms 7L of the bifurcated rod. f, and 95 45 employed, that illustrated consisting of the said arm j is held at such an angle by the threaded rod e, which passes down through an spring m, secured to said arm and to the seat opening in the top of the fount, the lower end n in said bifurcated rod f, said spring tendof said threaded rod having the shoulder e2 ing to force the arm j up and consequently formedthereon,said shoulderbeingheld withthe fingers 7e down into engagement with a roo `5o in a seat c3, being in the bottom of said lamp iiange Z.

and adapted to be rotated therein. The up- From the construction above described it is apparent that when the several parts of my improved wick-raising device have assumed the position shown in full lines in Fig. 1 the teeth i2 of the clutches z' will be forced into .be elevated, and with it the wick d, traveling up over the tube. It' it is'desired to remove the wick, the wick-raising rod e is turned and the bifurcated rod f raised until the U-shaped armj comes in contact with the top of the fount, when by a still further upward movement of the bifurcated rod f sufficient pressure is exerted upon the said arm j to overcome the resistance of the spring mand toV force down the said arm j. This depression of the armyl will throw up the fingers 7c and free them from engagement with the fianges Z, as shown in dotted lines in Fig. l. As soon as the fingers 7c have been raised beyond the vertical portions t" of the clutches 71 said clutches will be free to swing readily in their bearings. The wick d can then be readily withdrawn from the tube, as the teeth i2 of the clutches c' are no longer forced and held in contact with said wick-body, and said clutches are free to lswing in their bearings and their teeth offer no resistance to the Withdrawal of said wick.

Vhen the wick has been removed and a new one adjusted, and when said wick has been applied tothe tube ,and has reached a distance below the teeth ft2 ot' the clutches t', the Wick-raising rod is again turned and the bifurcated rod lowered, which operation will allow the springs m to force up the arm j, and

consequently cause the fingers 7o to again en` gage with the flanges l, and so lock the clutches rigidly in their bearings, forcing the teeth 712 of said clutches into the body of the wick, when the wick may be further lowered within the fount.

In the modified form of releasing device (shown in Fig. I am enabled to dispense with the spring m. In this case a releasing! upon said army' will force said arm down-'and so release the fingers 7o. The arm j by this operation is brought to substantially a horizontal position, and upon its descent it will engage with the tripping-lug q, which will force up said armjand cause the fingersk to again engage with the flanges Z. When the said arm j has reached its maximum height, it will free itself from the hooked portion r when any obstruction to the descent of the wick-raiser is removed.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. In a wick-raising device, the combination, with the wick-raising rod, of a bifurcated rod secured thereto, clutchesjournaled in said bifurcated rod, and mechanism supported on said rod for locking said clutches to hold them rigidly in contact with the wick and for automatically releasing said clutches, substantially as and for the purposes set forth.

2. In a wick-raising device, the combination, with the wick-raising rod, of a bifurcated rod secured thereto, clutchesjournaled in said biturcated rod, and U-shaped arm pivoted to the arms of said bifurcated rod, said U -shap'ed arm having fingers thereon engaging Iwith said clutches and locking said clutches to hold their teeth rigidly in contact with the wick, substantially as and for the purposes set forth.

3. In a wick-raising device, the combination, with the wick-raising rod, ot' a bifurcated rod secured thereto, clutches j ou rnaled therein, a U-shaped arm pivoted to the arms ot said bifurcated rod, said arm havingfingers therein engaging with said clutches to lock said clutches rigidly in their bearings, and a spring for holding said fingers firmly in engagement with said clutches, substantially as and for the purposes set forth.

4. In a wick-raising device, thecombination, with the wick-raising rod, of a bfurcated rod secured thereto, clutches journaled therein having inwardly-projecting teeth, a U- shaped arm pivoted to the arms of vsaid bifurcated rod, Isaid'arms having fingers thereon engaging with flanges formed on the ends of said arms of said bifurcated rod, and a spring for holding said iingers in engagement with said flanges, substantially as andforthepurposes set forth.

j In testimony whereof I, the Said WILLIAM M. I-IOERLE, have hereunto set my hand.
